摘　　要：华1037S是以光温敏核不育水稻C815S为轮回亲本,以携带Pi2基因的抗稻瘟病材料VE6219为供体亲本,通过杂交、回交和分子标记辅助选择,并结合低温筛选和人工气候箱鉴定选育的抗稻瘟病中籼型光温敏核不育系,具有株叶形态好、中抗稻瘟病、育性稳定、育性转换临界温度低、配合力与C815S相当等优点,2013年8月通过湖北省科技厅鉴定。Hua 1037S, derived from the cross of C815S, a photoperiod and thermosensitive genic male sterile （PTGMS） line in rice, and VE6219, a donor of blastresistant gene Pi2, and developed by the backcrossing meth od （using C815S as the recurrent parent） plus the molecular marker assisted selection for Pi2 and fertility identifi cation under low temperature stress in phytotron, is a new medium indica PTGMS line with blast resistance in rice. It is characteristic of good plant type, moderate blast resistance, complete and stable sterility, low critical tempera ture for fertility alteration and similarity to C815S in combining ability. In August, 2013, it was technically identi fied by the Science and Technology Department of Hubei Province.
